1o @ZZ whom t may concern.' Be it known that I, JOSErrI SUNNEN, a citizenof the United States of America, a resident of the city of Mexico', yAudrian county, and State of Missouri, have invented certain new and useful Improvements in Valve-Lifters, of which the following is a specification containing a full, clear, and lexact description, reference being had to the accompanying drawings, forming a part thereof. I

My invention relates to improvements in valve lifters, and has for its primary object a valve lifter having its jaws constructed of spring material so that by the tightening or loosening of a nut the jaws can be readily adjusted for different sized valve stems or washers. Y

A further object is to construct la valve lifter having jaws in such a manner that when the same has compressed a valve spring, the spring can be held in that position any desired length of time.

In the drawings: v

Figure 1 is a side elevation of my device showing the same applied to an engine valve. A.

Fig. 2 is an enlarged top plan view of my device.V

Fig. 3 a cross line 3-3 of Fig. 2. A

Referring to thedrawings,4 indicates a portion of an engine cylinder, 5 the valve, 6

the valve stem', 7 the valvespring, 8 the4 washer against which one end of the spring rests, 9 the Cotter key for holding the spring and washer on the valve stem, and 10 the upper end of the push rod, which operates the valve. y.

My improved valve lifter isl constructed of two sections or jaws 11 and 12 which are preferably each 'f U-shape, having their forwardly extending ends 13 parallel with each other and united by the base or uniting portions of the members 11 and 12. The forwardly extending .substantially parallel portions of the jaw members 11 land 12 .are preferably formed with inturned anges 14 that form resting surfaces for the washer 8 on the valve stem and bearing surfaces resting against the push rod 10 or a surface of the cylinder a, respectively. The base or doubled end of each jaw section is formed sectional view taken on the with a lateral projection, that of the section 1.1 being designated 15, and that of the sect1on 12, 18. One of these projections, .the one designated 15, is formed with a pair of Patented Feb. e2, 1921.'.

PATENT;

perforated ears 16, andthese lie, when the parts of the device are assembled, opposite to and overlap the heel of thel other jaw section, and a pivot bolt or rivet 17 passing through these overlapping parts unites Vthe two jaws. The extension 15 carries, near its heel, a threaded nut or boss 19, in which i is adjustably seated a thumb screw 2O, the end 21 of which bears against the rear face 22 of the projection 18 near its outer end. It will be seen that the VU-shaped jaw sections 11 and 12 lie one within the other and that the end of one of the lateral projections 1s plvoted at its outer vend to the other section where the lateral projection carried by such other jaw unites with the two parallel forwardly extending arms thereof. The

parts 11 and 12 are preferably formed of sheet metal and hencecan be easily shaped, and when thus made the forwardly extending arms thereof arek resilient and hence capable of adjustment toward and from each other.

From thisconstruction it will be seen that when the thumb screw'20 is driven inward thel pressure exerted against the face 22 will spread the jaws 11 and 12; i. e., force them apart'. and thus raise the washer 8 and compress the spring'when thekey 9 can be withdrawn andthe valve 5`removed from the engine cylinder. `The jaws 11 and 12 are each provided with perforations through which a bolt23 passes. This bolt is provided with the nut 24, and by either tightening or loosening this nut, the ends 13 of the jaws 11 and 12 can be either spread apart or' drawn' together, the spreading being'caused entirely by thespring material of which the jaws are composed.

With my device it is possible .to remove the valve 5 from the engine without removing thevalve lifter, and thus the washer 8 and valve spring 9 willalso remain i'nltheir proper positions, and there is no .chance of losing the same, especially thewasher, which is frequently done where the spring1 and 'washer have to be removed and laid on the work-bench before the valve is removed from the cylinder.
